关于性能优化:记录一次快速注册接口的优化

5次阅读

共计 5988 个字符，预计需要花费 15 分钟才能阅读完成。

旧版本：PHP 语言实现, 应用屡次 DB 查问来生成一个用户名，再 DB 查问用户表，确保用户名未反复

新版本：PHP 语言实现, 从 Redis 间接获取一个可用用户名，注册时候再判断是否未反复

Go 版本：Go 语言实现，其余统一

这里的优化次要有两点：

1. 次要是采纳发号器的思维，预生成可用的账号，而不是每次用的时候才生成

2. 把判断是否未反复滞后，真正实现注册的那一步才去判断，因为很多用户下载了游戏，未必走到注册那一步，大略只有 80% 出头的激活注册率

ab 压测各情景下均屡次压测，取较两头值的一次数据
